To all whom it may 0mm Be a known thatI, Diva r. Meant,

a citizen ofIthe United States, Dunmore,

residing at Selvage-Trimmmg Machines, 3 of xzwhich the followingv is a specification;

objectto provide improved means for cutting or trimming the longitudinal'ed'ges of wall paper without-lmrolling th'e same. i

rovide means whereby wall paper may be trimmed evenly or smoothly before :the paper h'as been, un-

adating and cutting rolls of various sizes.

My. invention still further rolls of wall paper,

whereby the same are the cutting operation, sing a clean and even cut.

A still further ob'ect of m'y is to provide a device as above brieflyde',

scribed,c-further characterized by an im proved cutting element, adapted for use in 1 connection with the device and wherein the longitudinal edges of rolled wall paper, or v other similar material,may be trimmed eflispecial skill being displayed by the operator. With these objects in view, together with others which will appear as the description proceeds, my invention'consists in the novel combination and arrangement of parts, all as will be more fully described hereinafter, and particularly pointed out in the claims hereunto appended. i

with reference to the accompanying drawings wherein I have shown a practical embodiment of the same, and in whichs Figure 1 is a perspective view of the wall paper roll supporting device, Fig. 2 is an enlarged transverse section, line 22 of Fig. 1, and looking in the direction-indicated by the arrows, Fig. 3 is an end view of the device illustrated in Fig. 1,

Referring now more particularly to the drawings, 1 represents the body portion-of p the improved wall paper trimming device, Thls lnventlon relates to wall. paper, trimming devices, and has for its primary which-may be constructed as shown of' a to a wall or other ,stati'onary support by means i of securing members, such as are shown at 2. TlllSblOCklS provided, preferably at its forward side and near thetop, with 'a longitudinally extending channel '3,

of sufficient breadth-to accommodate the usual. standard size rolls 1 of wall paper.

Securedtooneend of the'block 1, and ex-' tending transversely thereof, .is a plate 4, formed preferably 'of me'tal, and provided near its center, or at such point in its sui face as to .register-withsaid channel, with an opening 5. This plate may be secured to the block 1 in any preferred manner, screws 6 being provided in the present instance,

and having theirv heads counter-sunk to pre sent a smooth outer surface-to the plate 4'. r

As an. improved means for rigidly sup--- porting the paper roll within. the channel' 3, 7 adjacentione endof,

theblock within which is -threaded a paper a clamping screw 8. It is to beobserved that the bracket 7'spans thechannel 3 in order that the paper clamping element may most e'fficiently engage the paper roll,andit is also tobe noted that a disk 9 is provided upon-the endof the screw paper :from becoming torn while being clamped within the channel. As a con venient and efficient means for securing the paper roll opposite end of theblock I provide a flexible member 10, in the form of a chain. This chain is secured as at 11 at one of its ends i a I to the upper surface oftheblOc'k, the oppo- My invention will be better understood" site'eiid being provided with a ring 12 whereby the same may be engaged conveniently with the finger. A peg 13 is located upon the forward face of the block 1 for securing the chain through its various It is obvious that this arrangement provides an efficient means for securing the end of the paper roll within the channel 3, capable of accommodating rolls of various sizes, and yet which may be quickly and 8 to protect the within the channel adjacentthe easily attached and detached to permit of V 20 edge 16 of the blade is the ready application or removal of a roll to or from the channel 3. It is also apparent that the clamping member at the opposite end of the block 1 is capable of quick and 5 easy adjustment, and yet which securely holds the roll within the channel.

In Fig.4 of the drawings I have illustrated a knife which I find most practical in the paper trimming process, and which comprises a comparatively short narrow blade 14,; provided at the opposite ends with out warolly extending handles whereby the blade may be easily manipulated with the hands. These handles are preferably swiv- 15' eled upon the twists of made during the cutting operation. It is also to be observed that the knife is curved transversely, or hollow ground, whereby the kept in sharp condition by its continual frictional engagement withthev plate 4 upon the block during the cutting process.

It is to be understood that when it isfor-any reason to trim the found necessary longitudinal edges of a wall or other paper, the roll is inserted within the channel 3 of 7 the block, with the end thereof protruding beyond the outer face of the plate 4 such distance as it is desired that the edge be trimmed. The clamping screw 8 is then operated. to hold the the remote end of the block, while the chain 10 is drawn across the paper near the oppositeend of the block and is secured at its free end by engagement of one of its links over the peg 13 to hold the paper roll rigid near the end to be cut. The knife 14 is then graspedin the hands by the handles 15 with 40 the cutting edge 16 engaging the protruding end of the paper roll. In operating the knife the same is held firmly against the smooth outer face of the plate 4, sufficient inward pressure against the paper rollbeing imparted to the knife to cut through the several thicknesses of thesame at each move- I ment around the circumference of the roll.-

j It will be readily seen that a clean and accu rate severance of the paper may be had by this arrangement, and it is obvious that by reason of the paper roll being so positioned upon the block as to be spaced from the blade in order that various the blade may be conveniently paper roll in position at wall or support to which the device is attached, access may be had from all points in the circumference of the roll during the cutting operation. It is also to be observed that the plate 4 most face of the of the same are l. In a device of the classdescribed, a
